DOOR LATCH MECHANISM Application filed Ju1y 28, 1930. Serial No. 471,369.-

This invention relates generally to remote control mechanism for vehicle door latches and the like, and consists of certain novel features of construction, combinations and arrangements of parts that will be hereinafter more fully described and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a fragmentary elevation of a 10 Vehicle door With remote control mechanism embodying my invention applied thereto;

Figure 2 is a transverse, sectional View through the door above the latch mechanism;

Figure 3 is an enlarged fragmentary elevation of the remote control mechanism per se;

Figure 1 is a top plan view of the construction illustrated in Figure 3; Figure 5 is an end elevation of the construction illustrated in Figure 3.

Referring now to the drawings, 1 is a vehicle door of conventional design-having spaced pillars 2 and 3 respectively and a'connecting lock board or belt panel 4. 5 is a latch case plate secured to the outer face of the pillar 2 and provided with an opening 6. 7 is a substantially U'-shaped latch bolt pivoted upon a pin 10extending vertically through spaced inturn-ed lugs 11 and 12 re spectively of the case plate and movable through the opening 6. Preferably the spaced sides 13 and 14 respectively of the latch bolt are provided at their inner ends with thelaterally projecting flanges 15 and 16 respectively. A spring 17 is sleeved upon the latch bolt pivot pin 10 and has laterally projecting portions 18 and 19 respectively bearing against the case plate and side 13 of the latch bolt for normally holding the latter in projected position. A rollback 20 operable from the outer side of the door by a suitable handle 21 is engageable with the lateral flange 15 to effect the retraction of the bolt against the tension of the spring 17 while a crank portion 22 of a remote control rock arm 23 is engageable with the lateral flange 16 to effect the retraction of the latch bolt spaced. plates 24: and 25 respectively upon the inner side of the belt board 4 and is'provided at its inner end with a relatively short straight arm portion 26 that extends through and is'movable vertically lIllfi, vertically extending slot 27 in the plate 25. Extending through an embossed portion 28 of the, plate 25 is a stub shaft 29 that is provided at its inner end with a squared portion 30; A remote control handle 31 is rigidly secured to the squared portion 30, while a substantially 'heartshaped cam 32 is rigidly secured to the stub shaft at the-inner end thereof and is provided directly above the "shaft 29 with an opening 33 that receives the inturned arm portion 26 of the rock arm 23., In the present instance, the opening 33 is inverted heartshape and is provided at its opposite side edges with connecting longitudinally curved inwardly projecting flanges 3A and 35 reportion 26 of the rockshaft will be engaged MANUFACTURING COMPANY, OF DETROIT, MICHIGAN, A CORPORATION ,OF MICHL and moved downwardly into,v a horizontal plane by the cam surface '35 and this will cause the crank port-ion 22 to retract the latch bolt. When the stub shaft 29 is turned tot-he right by the handle 31 the arm portion 26 of the rockshaft 23 will be engaged and forced downwardly into a horizontal "plane by the cam surface 341 and this will .cause the crank portion 22 of the rockshaft to retract the bolt. Thus the stub shaft 29 is movable about a horizontaLaXis and simulates the movements of operating handles of conven: tional remote control mechanisms with which the operators of 'motor vehiclesare' familiar.

Moreover, Y the latch mechanism is simple in construction, may be economically manufactured and can be readily installed. w

What I claim as my invention is z 1. In a door latch mechanism, the com bination with a latch bolt, ofr'emote control means for actuating said boltfincluding a rockshaft engageable with the bolt, a stub shaft at substantially right angles to said rockshaft, and a driving connection between said shaft including a cam on the stub shaft engageable with the rockshaft.

2. In a door latch mechanism, the combination with a latch bolt, of remote control means for actuating said bolt, including a rotary operating member, and a connection between said member and bolt including a rockshaft, and a cam associated with the r0 tary member and engageable with the rockshaft.

3. In a door latch mechanism, the combination with a latch bolt, of remote control means for actuating said bolt, including a rotary operating member, a cam operable by said member, and a rockshaft operable by the cam and engageable with the bolt. 4. In a door latch mechanism, the combination with a latch bolt, of remote control means for actuating said bolt, including a plate remote from the bolt, a stub shaft journaled in the plate, a cam carried by the stub shaft, and a rockshaft engageable by the cam and engageable with the bolt.

5. In a door latch mechanism, the combination with a latch bolt, of remote control means for actuating said bolt, including a plate remote from the bolt, a stub shaft journaled in the plate, a rockshaft having laterally extending portions respectively extending through the plate and engageable with the bolt, and a member carried by the stub shaft having a cam surface engageable with one of the laterally extending portions aforesaid of the rockshaft.

6. In a door latch mechanism, the combination with a latch bolt, of remote control means for actuating said bolt, including a plate remote from the latch bolt, a stub shaft journaled in the plate, a member rigid with the stub shaft and having opposed cam surfaces, and a rockshaft having a laterally extending portion engageable with the cam surfaces aforesaid of the member on the stub shaft and having another portion engageable with the latch bolt.

7. In a door latch mechanism, the combination with a latch bolt, of remote control means for actuating said bolt, including a plate remote from the latch bolt, a stub shaft journaled in the plate, a member rigid with the stub shaft and having a cam surface, and a rockshaft having a portion extending through the plate and adapted to be engaged by the cam surface of the member on the stub shaft and having a laterally extending crank portion engageable with the latch bolt. 8. In a door latch mechanism, the combination with a latch bolt, of a plate remote from the bolt, a rotary operating member carried by said plate, and an operating connection between said member and latch bolt including arockshaft, and a cam operable by the rotary member for actuating said shaft.

9. In a door latch mechanism, the combination with a latch bolt, of a plate remote from the bolt, a rotary operating member carried by said plate, and an operating connection between said member and latch bolt includ ing a cam carried by said operating member, and a rockshaft having a portion engageable by said cam and having another portion engageable with the latch bolt.

10. In a door latch mechanism, the combination with a latch bolt, of remote control means for actuating said bolt, including a plate remote from the latch bolt, a stub shaft journaled in the plate, a member rigid with the stub shaft and having a cam surface, and a rockshaft having a portion adapted to be engaged by the cam surface of the member on the stub shaft and having a portion engage able with the latch bolt.

11. In a door latch mechanism, the comd bination with a door latch bolt, of remote control means for actuating said bolt including a stub shaft, a member operable by said shaft and having opposed cam surfaces, and

a rockshaft having an arm portion engagev bination with a latch bolt, of means for actuating the bolt including a roclrshaft, and a swingingly mounted member having a cam surface engageable with the rockshaft.

In testimony wherof I aiiiX my signature.
